This is getting off topic, but know that weight loss will not magically improve your skating. That logic has pushed so many into disordered eating patterns and eating disorders when it's literally not true. While weight impacts performance (sometimes by a lot as Sandra said), it's rarely at the forefront of an issue.
Weight should be kept between a doctor and patient and sometimes a coach educated in health. Without a qualification or education in the health field, no one has any business telling anyone that they need to gain or lose weight.
Skaters, if your coach is telling you that you need to lose weight to land a jump or skate better, find a new coach and check in with a doctor if you're concerned about your weight.
